Why make a Patriot Pro clone?
I'm starting to rethink one of my 2023 rocketry projects. Years ago I bought a 3" body tube and nose cone from North Coast Rocketry (when it was a part of Estes, ~1998) with the idea of building a Patriot Pro clone using a 4 X D12 engine cluster. However, after reading a history of the Estes Pro Series on Ye Olde Rocket Forum I realized this was silly. The excess weight of the four engines would make this a marginally stable rocket which would be unlikely to go very high, even on 4 E12 engines. Four D engines = 1 F engine; four E engines = 1 G engine, but four E engines have a high likelihood of at least one of them experiencing catastrophic failure (CATO) and I can buy anything up to a G engine without Level 1 certification from Apogee and other vendors. A better use for this body tube and nose cone would be to build a clone of an Estes Leviathan , with a 29 mm engine mount capable of taking Estes E & F engines and larger AeroTech engines (up to G).
